WHEEL-PLOW.

SPECIFICATION forming part of Letters Patent No. 269,002, dated Decemberl2, 1882.

Applicntonled May 20, 1882. (No model.) i

To all whom itrmay concern Be it known that I, FRANKLIN O. BRYAN, acitizen ofthe United-States, anda resident of \Vinona, in the county ofWinona and State ot' Minnesota, have invented a new andvaluableImprovement in W'heel-Plows; and I do hereby declare that thefollowingis a full, clear, and exact description ofthe construction and operationotv the same, reference being had to the annexed drawings, making a partof this specification, and tothe letters and figures of reference markedthereon.

Figure l ot' the drawings is a side view ot' this invention. Fig. 2 is aplan view of the same. Figs. 3, 4, and 5 are details ofthe con'-strnction.

This invention has relation to wheel-ploivs; and itconsists in theconstruction and arrangement ot' parts, as will be hereinafter fullydescribed and claimed'. l

In the aecompanyingdrawings, the letterD represents the tongue-frame,which is of rectangular i'orm, raised in rear, and consists principallyot' the i'ronttransverse bar,a,theraised rear transverse bar, b, theside bars, c, and the middle'bar, d, to which the seat-standard S isfastened.

F and I1" indicate the {dow-frames, which are independent ot each other,and are laterlally arranged one on each side of the center. These framesare similar in form, one being designed for the right-hand plow andtheother for the left.

Each frame consists of a rear transverse bar,

e, and extending forward therefrom an inner arm, g, and an outer arm, h.

The frame-work is of wrought-iron, and the three sections D, F, and F'are pivoted together in the following manner: The inner arms, g, ot theplow-frames are pivoted to each other and to a central bearing, G, ot'the frame D by means ot' the transverse bolt le, and the outer arms, h,are pivoted to the side bars, c, of the tongue-frame by the bolts l. Thearms It extend forward ot' the pivots l, and are provided with thelever-handles I, which are iirmly securedin position with relation tosaid arms by braeesK.'

The tongue-frame is provided on each side with a toothed quadrant, m, toengageaspringcatch .on each lever, whereby the relative position ot'each plow-frame after adjustment is secured.

The axlesA are locatedin rearot the pivotal connections oftheplow-frames with the tongueframe, and are securely bolted respectivelyto the arms ot' each frame by means of the U- shaped bolts p and nuts n,as indicated in the drawings. The wheels W therefore have independentaxles, one being carried by each plow-frame. v

B B designate the plow-beams, which are connected at a point above thefront ends ot' the plows, or at any point the plows work best, to therear bars, e, of the plow-trames by means ot' clamps s and verticalparallel bolts t,which `are located one on each side ot' the plow-beamand extend through pert'orations r in the rear bar of the frame. Asingle hook-bolt may be. used in place ofthe two bolts. This is the.only fasteningemployedinconnectingthebeam,and itis designed to allow thebeam to have a lateral vibratory lnovemen t, so that each plow will beself-adjusting, always keeping in the line ot' draft. i The forwardendsotl the plow-beams extend Yunder the axles and bear against them.

Only one of the plows is intended to be used at .l

a time, the other being elevated, so that this con struction constitutesa side-hill plow. When the plows are not in use they are raised by meansot' the levers 1, and are held inthe raised position by thelever-catches and the quadrants of the frame D. Byraising its lever4either plow-frame canl be dropped in Working position, together with itsplow, and its wheel is'at the same time depressed or set lower asrequired. The low wheel always ruins in the furrow just turned, so thatthe machine is kept level.

T and T indicate the two tongues,which are secured to the sides of theframe D by pivotbolts o', extending vertically through the framebarssome distance in rear ot' the front bar, o, of the frame. These tonguesresten theframe D, extending through the elongated trailsverse bearingsformed between the ends of the lfront of the frame and the raised strapsH,

which are secured thereto. Perforations a and b are made through thestrapsand the bar ato receive the vertical boltsz and z', wherebythetonguesarefastenedinposition. Then three horses are employed the tonguesare adjusted in parallel position, `extending straight forwaxd, and areheld by the boltszz. When two horses are to be used the tongues areadjusted in oblique position, as indicated by the dotted lines, so thattheir ends will meet in front. ln making either adjustment of thetongues the bolts z z are to be removed, and then replaced after thetongues have been arranged in the desired position. y

Independent plow-frames, each pivotedto the rong'ue-frame-and eachcarrying the axle ot one w heel, have been used prior to my invention,and said construction isnot broadly claimed herein.

Having described this invention, what I ffl-ann, and desire to secure byLetters Patent, 1s-

l. In a Wheel-plow, the. combination,with the lateral plow-frames F Fand their independent yframe, D, its quadrants m. and tongues T T',

the lateral independrnt plow-frames F F', pivoted to said front frame,their levers I, axles A, and Wheels W, and the plow-beams B and theirplows, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my nainein the presence of two witnesses.

FRANKLN C. BRYAN.
